We compare the welfare effects of different regulation schemes of electricity distribution utilities. The regulation schemes are price cap regulation, cost of service regulation, menu of cost-contingent contracts and simple menus of contracts. In our calculations we utilize the benchmarking information of firm specific costs. The firm specific cost information of Finnish electricity distribution utilities is obtained by using various Stochastic Frontier models. Our basic result is that welfare can be improved by changing the cost of service regulation scheme to the menu of contracts regulation. Welfare also increases in the case of price cap regulation. There is however, a significant difference among regulation regimes on how this improved welfare is distributed to consumers and producers.
